Value Collection CR-21-12 Cartridge Roll Mandrel

Product Description

The VALUE COLLECTION CR-21-12 is a quick-change cartridge roll mandrel designed to hold and drive cartridge rolls during deburring, blending, and surface finishing operations. The mandrel features a 0.25-inch pilot diameter with a 1-inch pilot length, and a 0.25-inch shank diameter with a 10.25-inch shank length. Overall length is 12 inches. The quick-change design allows for fast cartridge roll swaps without removing the mandrel from the tool, keeping workflow efficient on the shop floor or in the field.

It is appropriate for both bench and portable tool setups where cartridge rolls are used to finish bores, contours, or weld seams. Machinists, fabricators, and maintenance technicians handling metal prep and surface conditioning work are the primary users of this tool.
